Host-status of 20 sweet potato lines to Meloidogyne species in South Africa

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2020
Experimental system: Due to serious economic challenges posed by root-knot (Meloidogyne species) nematodes in sweet potato (Ipomoea batatas) production, the Sweet Potato Programme (SPP) of the Agricultural Research Council (ARC) in South Africa has since

Suitable rootstocks for organically grown tomato and cucumber in relation to Meloidogyne SPP. [PDF]

, 2011
In organic greenhouse vegetable production, significant yield loss occurs due to root-knot nematodes (Meloidogyne spp.). Soil steaming is effective; however, it is not preferred, since beneficial soil micro organisms are eliminated.

Amendment of Potting Soil With Black Soldier Fly Byproducts Affects Fungus Gnat Development

Entomologia Experimentalis et Applicata, EarlyView.
The study's three experiments were conducted in accordance with the development stages of fungus gnats, with adults emerging from the four treatment substrates and being caught on sticky cards as a common indicator. The treatments were formed from peat‐free potting soil, either pure or supplemented with combinations of byproducts from black soldier fly

Potential of the Predatory Mites Gamasellodes lavafesii (Mesostigmata: Ascidae) and Cosmolaelaps mediocuspis (Mesostigmata: Laelapidae) on Different Soil Pests/Parasites and Alternative Prey for Large‐Scale Rearing

Journal of Applied Entomology, EarlyView.
ABSTRACT Many species of Mesostigmata soil mites have potential as biological control agents of pests/parasites. This study evaluated the predation potential of two of these species, Gamasellodes lavafesii (Ascidae) and Cosmolaelaps mediocuspis (Laelapidae).

CONTROLE DE MELOIDOGYNE JAVANICA COM PASTEURIA PENETRANS [PDF]

Pesquisa Agropecuária Brasileira, 1999
Objetivou-se, com esse trabalho, avaliar a eficiência de Pasteuria penetrans no controle de Meloidogyne javanica em condições de casa de vegetação. Os tratamentos eram compostos de quatro níveis de inóculo de P. penetrans, 0, 10x10(5), 50x10(5) e 100x10(5) endósporos/kg de solo autoclavado. Imediatamente após a inoculação da bactéria P.

Effects of Meloidogyne incognita on agronomic parameters and structural changes in eggplant (Solanum gilo Raddi) roots treated with Purpureocillium lilacinum

Plant Biology, EarlyView.
Meloidogyne incognita impairs eggplant growth through gall formation with changes in root cell wall components and vascular tissue disruption, while the biocontrol agent Purpureocillium lilacinum mitigates these effects by reducing nematode infection. Abstract Meloidogyne spp. induce structural changes during the development of root‐knot galls, leading

Interrelations between commercial beetroot (Beta vulgaris) cultivars and Meloidogyne species

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2017
Most beetroot (Beta vulgaris) cultivars in South Africa are exotic and were specifically bred for root-knot (Meloidogyne species) nematode populations in their countries of origin.

Meloidogyne javanica Chorismate Mutase 1 Alters Plant Cell Development [PDF]

Molecular Plant-Microbe Interactions®, 2003
Root-knot nematodes are obligate plant parasites that alter plant cell growth and development by inducing the formation of giant cells for feeding. Nematodes inject secretions from their esophageal glands through their stylet and into plant cells to induce giant cell formation.
